Programmable Tattoos

As an alternative to a flexible wearable display, how about a subdermal display? Or else one painted onto the skin? OhmyNews.com, a source for some occasionally startling tech news, reports that this may be in our future.

There was only a brief mention of my favourite option (video), but more details on another technique which would paint three thin layers onto the skin: two conductive matrices aligned orthogonally to each other, with a special ink solution between the two. It’s a pretty cool read, and lends hope to those of us who hope to have digital clocks glowing through our skin before too long.
